Hallow Dear,

From your history, I understand that you had unprotected sex on day 4 of your menstrual cycle and you started your next pack pills on day 3.

On day 4, the egg is not released as yet. It is released 14 days before the next expected menses if you are not on birth control pills. The egg has a life of 24 hours while the sperms are active for 72 hours. Hence a period of about a week around the day of ovulation is fertile window. Your intercourse was far away from this period. So the pregnancy chances due to this intercourse are almost nil.

However, if you want to have the evidence, you may opt for Beta hCG test 10 days after the day of intercourse. Pregnancy is diagnosed by the values more than 25 mIU/ml while in non-pregnant state, the values are less than 5 mIU/Ml.

Alternatively, you may wait for your menses. If they appear, you are not pregnant. If your menses are delayed, you may opt for pregnancy test on the overnight first morning urine sample; earlier the test may report false negative.

I hope this helps you.
